In the dying days of the wild west of Red Dead Redemption II an outlaw's most useful asset is a well-trained horse. For Arthur Morgan a horse is more than a utilitarian mode of transport, it's a trusted friend with whom a deep connection is forged over the course of his story. For the developers of Red Dead Redemption II, delivering a believable stable of horses that lived up to the memories of Red Dead Redemption was a critical part of the player's experience.


The audience will develop an understanding of how Rockstar's interdisciplinary team approached the design and implementation of movement and styling for naturalistic horses in Red Dead Redemption II. They will leave with insight into Rockstar's development process and knowledge of concepts for improving quality and feel of character animation systems.

Intended Audience

The intended audience is all levels of AI/Gameplay/Animation programmers and technical animators interested in technology and techniques used for high-quality animation and movement in games. Some familiarity with current techniques of applying and controlling animation in games, such as blend trees, is useful.
